During the past 10 years, 15 patients have had percutaneous catheter drainage (PCD) of pyogenic liver abscesses (PLA) at a major teaching hospital. Five PLA were related to biliary tract disease, two were secondary to
colonic diverticulitis
, two developed after abdominal surgery, and the remaining were associated with hepatic trauma, gastric ulcer, Crohn's ileitis, and
colon cancer
. Two abscesses were cryptogenic. Mean diameter of PLA was 8 cm and ranged from 2-14 cm. Three patients had multiple PLA. All patients were initially treated by PCD without major complications. However, one patient required a second PCD after developing a recurrent abscess. Fever and leukocytosis defervesced at a mean 3.6 days and 7 days, respectively, after PCD. Seven of the 15 patients subsequently had one-stage elective abdominal operations for treatment of diseases underlying PLA including two cholecystectomies, two colon resections, one gastrectomy, one ileostomy closure, and one laparotomy for unresectable gall bladder cancer. There were no postoperative complications. These results demonstrate that PLA are best treated by using PCD as primary treatment with surgical drainage reserved for patients who do not respond clinically to PCD. The need for operative treatment in diseases underlying PLA should not deter use of PCD as primary treatment.

Acute diverticulitis of the cecum and ascending colon, also called right-sided diverticulitis, represents a relatively rare disorder in the western hemisphere. Pseudodiverticula and, less frequently, solitary congenital diverticula are regarded as the underlying causes of acute diverticulitis. We report the helical CT findings in four patients with acute right-sided
colonic diverticulitis
. The CT was performed with a collimation of 8 mm, a pitch of 1.5 and an increment of 8 mm, and with variable administration of intravenous, oral and rectal contrast material. In two of the four patients, the acute diverticulitis was detected in the cecum and ascending colon, respectively. In two patients, the diagnosis could be confirmed during surgery and subsequent histologic examination of the resected specimen. On the initial CT studies, acute diverticulitis was correctly diagnosed in two patients and suspected in one patient without identifying an inflamed diverticulum. In one patient, the offending diverticulum in the ascending colon caused an inflammatory pseudotumor at the level of the ileocecal region. This process was initially mistaken as Crohn's disease. The CT diagnosis of a right-sided
colonic diverticulitis
is based on an inflamed diverticulum in the center of pericolic inflammatory changes and a preserved wall enhancement (target sign). Other CT findings, such as fatty pericolic infiltration and colon wall thickening, are rather non-specific and can also be found in a number of different ileocolic disorders, especially in
colon cancer
. In selected cases, the diagnosis can only be established by follow up CT after the pericolic infiltration has markedly subsided and an offending diverticulum has emerged.

Colonic diverticulitis
can present as mild abdominal discomfort or as life-threatening septic shock and can also mimic many inflammatory conditions. Most patients with acute diverticulitis can be managed with antibiotics and supportive care. Surgery is reserved for those with repeat attacks, disease unresponsive to medical therapy, certain complications, and the possibility of
colon cancer
that cannot otherwise be excluded.

Colonic diverticulitis
is a common condition in the western population. Complicated diverticulitis is defined as the presence of extraluminal air or abscess, peritonitis, colon occlusion, or fistulas. Multidetector row computed tomography (MDCT) is the modality of choice for the diagnosis and the staging of diverticulitis and its complications, which enables performing an accurate differential diagnosis and addressing the patients to a correct management. MDCT is accurate in diagnosing the site of perforation in approximately 85% of cases, by the detection of direct signs (focal bowel wall discontinuity, extraluminal gas, and extraluminal enteric contrast) and indirect signs, which are represented by segmental bowel wall thickening, abnormal bowel wall enhancement, perivisceral fat stranding of fluid, and abscess. MDCT is accurate in the differentiation from complicated colon diverticulitis and
colon cancer
, often with a similar imaging. The computed tomography-guided classification is recommended to discriminate patients with mild diverticulitis, generally treated with antibiotics, from those with severe diverticulitis with a large abscess, which may be drained with a percutaneous approach.

Laparoscopic surgery developed continuously over the past years becoming the gold standard for some surgical interventions. Laparoscopic colorectal surgery is well established as a safe and feasible procedure to treat benign and malignant pathologies. In this paper we studied in deep the role of laparoscopic right colectomy analysing the indications to this surgical procedure and the factors related to the conversion from laparoscopy to open surgery. We described the different surgical techniques of laparoscopic right colectomy comparing extra to intracorporeal anastomosis and we pointed out the different ways to access to the abdomen (multiport VS single incision). The indications for laparoscopic right colectomy are benign (inflammatory bowel disease and rare right
colonic diverticulitis
) and malignant diseases (right
colon cancer
and appendiceal neuroendocrine neoplasm): we described the good outcomes of laparoscopic right colectomy in all these illnesses. Laparoscopic conversion rates in right colectomy are reported as 12-16%; we described the different type of risk factors related to open conversion: patient-related, disease-related and surgeon-related factors, procedural factors and intraoperative complications. We conclude that laparoscopic right colectomy is considered superior to open surgery in the shortterm outcomes without difference in long-term outcomes.

Duodenocolic fistula (DCF) is a rare disorder defined by the presence of an internal fistula between the duodenum and colon.
Colon cancer
, Crohn's disease, diverticulum and duodenal ulcer are common causes of DCF, and vomiting and diarrhea are its main symptoms. We report a 14-year-old boy with DCF who had been treated for a functional gastrointestinal disorder (FGID). The boy had often experienced episodes of vomiting and diarrhea since infancy, and had been diagnosed with FGID. He was referred to our hospital because of a 2-month exacerbation of persistent vomiting and diarrhea. Upper gastrointestinal contrast revealed no abnormalities. Eventually, esophagogastroduodenoscopy detected a duodenal fistula, and DCF was diagnosed by endoscopic fistulography. Colonoscopy showed a diverticulum in the ascending colon near the fistula. In addition, a C
13
urea breath test for Helicobacter pylori infection was positive. One hypothetical pathogenesis of his DCF was perforated
colonic diverticulitis
. Adhesion between the fistula wall and colonic diverticulum near the fistula strongly suggested a relationship between the fistula and the diverticulum. However, he never presented with symptoms of
colonic diverticulitis
. Thus, a congenital origin was also suspected. After confirming temporary relief from the symptoms by endoscopic closure, surgical closure was performed.
